Interference Mitigation Techniques for Air to Ground Systems

1. A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna, comprising: adjusting a modulation symbol interleaving and/or forward error correction of an aircraft receiver interface in response to detected interference from a forward link of an interferer aircraft; reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and/or forward error correction does not mitigate the detected interference, from the forward link of the interferer aircraft, on communications received by the aircraft receiver interface from a serving ground station through the multi-beam array antenna; and providing aircraft internet service based on the communications received by the aircraft receiver interface from the serving ground station through the multi-beam array antenna.

2. The method of claim 1 , in which the interferer aircraft includes an aeronautical mobile satellite service (AMSS) transmitter.

3. The method of claim 1 , further comprising: assigning the aircraft receiver interface a portion of a communication spectrum that is unused by the interferer aircraft when reducing the data rate of the aircraft receiver interface does not mitigate the detected interference from the forward link of the interferer aircraft.

4. The method of claim 1 , further comprising: handing-off the aircraft receiver interface to a different ground station when reducing the data rate of the aircraft receiver interface does not mitigate the detected interference from the forward link of the interferer aircraft.

5. A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna, comprising: adjusting a modulation symbol interleaving and/or forward error correction of an aircraft receiver interface in response to detected interference from an interferer; reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and/or forward error correction does not mitigate the detected interference, from the interferer; performing antenna beam-steering away from a geographic (GEO) arc during an aircraft turn; and disabling an aircraft transmitter when a roll-angle of the aircraft turn is greater than or equal to a predetermined roll-angle threshold.
